Chronic Stress Can Damage Brain Structure And Connectivity

The news article I have decided to focus on is called â€Å"Chronic Stress Can Damage brain Structure and Connectivity†. The author, Christopher Bergland, discusses a study that was done at Berkeley and researchers discovered that chronic stress actually causes long-term changes in the brain. Bergland (2014) makes an interesting point in the beginning of the article about how children who are exposed to chronic stress are more likely that have problems with anxiety and mood disorders. A majority of the article focuses on the â€Å"revolutionary† experiments Daniela Kaufter, a UC Berkeley associate professor, conducted. These experiments are so significant because they show that â€Å"chronic stress and elevated levels of cortisol can generate more overproduction of myelin-producing cells and fewer neurons than normal.† Bergland (2014) then discusses the â€Å"grey matter† in the brain, which is packed full of nerve cell bodies and is where the brain does higher functions. He also discusses â€Å"white matter†, which is full of axons that connect neurons and makes a network of communications between different regions of the brain. The author (2014) says that the white matter in the brain is called that because the myelin sheath that surrounds the axons is white and fatty â€Å"and speeds the flow of electrical signals between neurons and brain regions.† Kaufer’s experiments focus specifically on the hippocampus, which is responsible for memory and emotions and can shrink under periods of stress.

Not only does FM impair life quality3, but it also increases disability and absence from work4. With the evolving diagnostic criteria of FM5, the prevalence rate is estimated about 2~4% in the general population with female predominance 6,7. Despite genetic, environmental and biochemical factors proposed as the underlyingRead More General Anxiety Disorder (GAD) Essay2269 Words   |  10 Pages Mental disorder, two simple words that can stir up a storm of emotions. Habitually mistaken by general society as â€Å"deranged† or â€Å"unstable†, the words mental disorder, often, tend to have a negative cognition associated with them. This should not be the case. The misunderstanding that mental disorder is automatically equivalent of that to being psychotic and erratic leaves many individuals feeling isolated, and distressed to share their helplessness due to fear of social stigma.

Considering its relatively recent discovery, the complete etiology and optimal biological therapies are yet to be elucidated. This review examines the neural correlates and biomarkers of PTSD along with biologicalRead MoreSymptoms And Symptoms Of Schizophrenia1858 Words   |  8 Pageshas been found through research that a person with schizophrenia has a different brain chemistry, neurotransmitter activity, and structure than a healthy human being. There is no single proven cause of schizophrenia, however there are several factors that contribute to the incidence of this disorder. It affects millions of people in the United States and is considered one of the most debilitating and disabling brain disorders. Both men and women are equally affected by schizophrenia in all culturesRead MoreAddiction Is A Complex Disease3403 Words   |  14 Pagesanalyzes how the brain and neurotransmitters influences our behaviors, thoughts and feelings. Our biology programs us to pursue pleasurable experiences, such as the euphoria felt when intoxicated. In biopsychology, addiction is viewed as a problem of brain functioning; we generally become addicted to the chemicals our brain releases, such as dopamine, not the substance itself. Through the use of self-help organizations, psychology and medication, the overall goal of abstinence can be accomplishedRead MoreEffects Of Maltreatment On Children And Children2057 Words   |  9 Pagesrelocated to alternative care arrangements, more commonly referred to as out-of-home care (OOHC). The research which investigates the effects of maltreatment on children, conclusively shows that experiencing trauma and/or neglect during childhood can result in considerabl e physiological and psychological effects on development across multiple key domains, such as cognitive, social-emotional, academic, and language (Perry, 2002; Perry, 2009; CFCA, 2014). More specifically, the literature surroundingRead MoreStephen P. Robbins Timothy A.
